In the year 2200, the earth's resources are exhausted and civilization has degraded. Weird stories about rules appear randomly, becoming a life and death game for various countries to compete for their national destiny. Pei Jiuce, a former criminal investigation consultant, was chosen as the Chosen One because of an unsolved case. He is calm and thoughtful, and is good at finding ways out of loopholes. Every time he enters the game, he may trigger the "crow's mouth" - a casual word will become a reality. Nine predictions, rewriting the rules. But he discovered that behind all the strange stories, there was a pair of high-dimensional eyes watching. If you win, the country's destiny will rise; if you lose, the city will be annihilated. He doesn't say it, because if he says it, it will be ineffective. Depressing words are his weapon, truth is his taboo. Nine times later, the rules bite back. He must find the source of those eyes before he is swallowed by the world.
